This card can be useful in Decks that don't necessarily rely on the Extra Deck, such as "Monarch", "Magical Musket", "True Draco", etc.
While controlling two or more monsters with the same original ATK, this card will prevent the opponent from declaring an attack, whatsoever.
Cards like "Magic Deflector" or "World Suppression" can be used to negate this card's negative effects during the turn it is activated; however, it would be vulnerable against effects that would destroy it.
Against a Deck that heavily relies on Special Summoning monsters and Field Spell Cards, this card can be given to the opponent with "Ancient Fairy Dragon", "Cosmo Queen, the Queen of Prayers", "Set Rotation", so that they wil be unable to use another Field Spell Card and if they choose to activate this card, those Special Summoned monsters will be destroyed.
